About Harry Hill, M.D.

Dr. Hill first came to the University of Utah in 1974 from the University of Minnesota as an Assistant Professor with an NIH grant directed at understanding the role of cyclic AMP and cyclic GMP in controling polymorphonuclear leukocyte and monocyte function in a variety of disease states associated with an unusual susceptibility to infection.  Subsequently, he turned his attention to host resistance against both group A and B streptococci, which are major causes of severe and overwhelming sepsis, pneumonia, septic shock syndrome, and necrotizing fasciitis.  He and his group first reported the absence of opsonic antibody to the various serotypes of group B streptococci as a major risk factor in early-onset group B streptococcal disease of the neonate.  Subsequently, he studied the role of whole blood transfusions and then intravenous immunoglobulin in the treatment of such infections in experimental animals and then in newborn infants in association with Dr. Robert Christensen.  He explored the functional activity of human monoclonal antibodies against the group B carbohydrate, which provided protection against the various serotypes of group B streptococci.  He pointed out the role of complement and, particularly, the C3dg component of complement in releasing marrow stores of neutrophils in group B disease.  He also was the first to describe the C5a-ase enzyme of group B streptococci (C5a-peptidase) which cleaves and inactivates the major chemotactic factor derived from complement – C5a.  Dr. Hill and his group then first pointed out the role of group B streptococci, a gram-positive organism, in releasing tumor necrosis factor contributing to the sepsis and shock that often accompanies infection due to these organisms. 

Dr. Hill’s lab was one of the first to demonstrate and describe the pathogenesis of abnormal neutrophil granulocyte movement in newborn infants and experimental animals.  He suggested that this was due to a deficiency in the production of interferon gamma, which could be corrected by recombinant interferon gamma and more recently the interferon gamma stimulating cytokines interleukin-12 and interleukin-18.  Neonatal mononuclear cells were shown to poorly transcribe mRNA for interferon gamma upon stimulation with group B organisms.  Working in the ARUP Institute for Clinical and Experimental Pathology, which Dr. Hill directs, he and his colleagues first developed a multi-analyte cytokine assay, which now can assess up to 14 different cytokines in 50-75 microliters of sample, which has allowed them to pursue the role of Th1 and Th2 lymphokines and monokines in promoting inflammatory and infectious disorders. 

Dr. Hill and Dr. George Veasy as well as other personnel at Primary Children’s Medical Center and the University of Utah have explored the large resurgence of acute rheumatic fever (ARF) that occurred throughout the Intermountain West surrounding Salt Lake City, which was published in the New England Journal of Medicine.  Recent follow-up studies on a long-term NIAID contract have documented the immune response to specific and nonspecific and cross-reactive streptococcal antigens, in ARF, using multianalyte technology.  A large number of samples from acute rheumatic fever cases, as well as, age-matched controls and uncomplicated pharyngitis patients, have been collected and are currently being analyzed for a variety of different humoral antibody, cytokine, and molecular abnormalities. 

More recently, working with Dr. Carl Wittwer and Dr. Karl Volkerding, Dr. Hill’s laboratory has began working on rapid molecular techniques for diagnosing immune deficiency diseases, especially chronic granulomatous disease and Job syndrome (Hyper IgE syndrome).
